f0 aZZ whom it may concern.-

Be it known that I, MENZO A-. RUTENBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oarbureters, of which the following is a specification.

This invention relates to carbureters for automobile and other engines, and is designed to produce a combustible mixture by causing the air to pick up and mix with the vapor of gasolene.

The object of the invention is to produce a superior mixture of air and gasolene and to automatically regulate the supply of gas as required by the motor.

I have shown a sectional elevation of my improved carbureter in the accompanying drawing, and referring thereto, 1 designates the mixing-chamber, which hasan outlet 2 leading to the explosion-chamber of the engine and both formed in a casting which also constitutes the top of the float-chamber 3. A v

float 4 is arranged within the chamber and is guided on the projection 5, which contains the nozzle 6, discharging into the mixing-chamber. A lever 7 is pivoted on a bracket 8 within the tank and has one end thereof, 9, weighted and arranged beneath the float and its other end engaged with the stem 10 of a valve 11, normally closing the passage 12, which communicates with the gasolene-supply. The valvestem 10 projects upward through the top of the chamber-cover, so that it may be operated by hand to increase the supply of gasolene within the chamber and commonly called tickling. The weight 9 is sufficient to counterbalance the stem 10, and consequently the valve will be promptly opened when the supply of gasolene in the chamber diminishes and the float falls.

An air-chamber 14 is located above the mixing-chamber within the body 14' and the tubular section 17 of the casting which incloses the mixing-chamber. To automatically regulate the supply of air, I-provide the pistonvalve 13, which operates in the air-chamber by the suction of the motor-piston and has openings 15 to register with the openings 16 in the'bod y lei. The lower end ofthe section 17 is extended down into the mixing-chamber,

adjacent to the concave bottom 18 thereof, so that the'air will be carried close to the gasolene and a better commingling thereof obtained.' The piston 'valve is normally held with the openings 15 and 16 out of alinement by means of a spring 19, arranged on the stem 20, which is fastened to the cross-arm 21. The upper end of the body is inclosed within a hood 22, which is provided with an inletopening 23.

Preliminary to starting the motor of an automobile it is customary to tickle the gasolene-valve, and this practice is followed with my carbureter for the purpose of providing a quantity of gasolene in the mixing-chamber l to be absorbed by the air which is sucked in when the motor-shaft is turned by hand in the usual manner. After the motor is once started the operation of the gasolene-valve and the air-valve is automatic, and the latter will be drawn down against the tension of its spring and the openings 15 16 caused to register to an extent corresponding to the speed of the motor-that i's to say, when the motor is traveling at a comparatively low speed the openings will not be fully registered; but when the motor istraveling at its maximum speed the openings will be exactly registered to admit the greatest quantity of air.

The invention also has relation to the particular construction, arrangement, and combination of parts herein shown and described, which are considered of prime importance in securing the desired results.

My improved carbureter operates automatically in exact proportion to the speed of the motor, and when the motor stops the valve 11 will be promptly closed by gravity to shut off the gasolene-supply. The construction and arrangement of the mixingchamber are particularly important; but I do not limit myself to the exact construction and arrangement of these parts or of any of the other parts, but reserve the right to make all such changes as fairly fall within the spirit and scope of the invention.

The carbureter is designed to produce a uniform mixture and in regulated quantities, so that the supply of gas is constantly apportioned to the speed of the motor.

Vithout limiting myself to the eXact construction and arrangement of parts herein shown and described, what I claim, and desire to secure by Letters Patent, is

l. A carbureter comprising a float-chamber, a float-valve therein, a mixing-chamber located above the float-chamber, a nozzle discharging upward from the float-chamber into the mixing-chamber, an air-chamber centrally disposed above the mixing-chamber and communicating with the mixing-chamber near the bottom thereof, and means for regulating the inflow of air to said air-chamber.

2. A carbureter comprising a float-chamber, a float-valve therein, a mixing-chamber above the float-chamber provided with a concave bottom, a nozzle discharging from the float-chamber into said mixing-chamber, an air-chamber communicating with the mixingchamber adjacent to its bottom, and a pistonvalve in said air-chamber.

3. A carbureter comprising a float-chamber, a float-Valve therein, a mixing-chamber formed in the top of said float-chamber and provided with a concave bottom and having a lateral outlet, an air-chamber above the mixing-chamber and formed partly by a tubular section which projects down into the mixingchamber adjacent to its bottom and below the top of the outlet, and a piston-valve in said air-chamber.
